Problems solved by technology

[0004] However, the existing steam distillation extraction has the following defects: one is that the water vapor will be partially condensed in the extraction tank during the extraction process, which reduces the amount of water vapor and the extraction effect; in addition, the extraction after steam distillation extraction The liquid also needs to undergo high-temperature redistillation to remove moisture to obtain the required volatile components, and the volatile components will be lost in the process

Embodiment 1

[0024] Such as figure 1 A kind of water vapor extraction device with silica gel column separation device shown, it comprises: extraction tank 9, and its outer layer has heating device 10, and its upper port communicates with the bottom of condensing tube 1 through distillation gas outlet 8, and its lower port passes through The water vapor outlet 11 is connected to the upper port of the water vapor generating device 12;

[0025] The upper port of the silica gel column 4 is connected to the lower port of the condensation pipe 1 through the condensate outflow port 3 , and the lower port is connected to the water vapor generating device 12 through the moisture outlet 6 .

[0026] The silica gel column 4 is filled with MCI silica gel 5 .

[0027] The outer layer heating device 10 of the extraction tank 9 is a water vapor heating interlayer.

[0028] The outer layer of the condensation pipe 1 is a condensed water interlayer, the condensed water inlet 2 is arranged at the lower pa...

Embodiment 2

[0032] Use the steam extraction device in Example 1 to extract the volatile components in the tobacco, the specific steps are as follows:

[0033] Put 500g of tobacco powder into a 5L extraction tank, add 1L of 5wt% citric acid aqueous solution (effect: a large amount of volatile nicotine and other alkaline substances are contained in tobacco leaves, if extracted, it will affect the quality of volatile components, lemon Acid is combined with alkaline substance to become an ionic compound, which is less volatile and has a density greater than water), and then the water vapor in the water vapor generating device is extracted, and the condensed water inlet of the condensation pipe is passed into cold water, and the water vapor becomes liquid water. Enter the silica gel column together with the volatile components, the water will not be absorbed by the silica gel, and the water will re-enter the steam generator through the water outlet, and the water will be recycled; the volatile ...

Embodiment 3

[0035] Use the steam extraction device among the embodiment 1 to extract the volatile components in the Radix Glycyrrhizae, concrete steps are as follows:

[0036] Put 500g of licorice powder into a 10L extraction tank, and then extract it with water vapor in the water vapor generator. The condensed water inlet of the condenser tube is fed with cold water, and the water vapor becomes liquid water, which enters the silica gel column together with the volatile components, and the moisture It is not adsorbed by silica gel, and the water re-enters the steam generating device through the water outlet, and the water is recycled; the volatile components are absorbed by the silica gel in the silica gel column. After the distillation is completed, the silica gel column is taken out, and the organic solvent ethyl acetate will absorb The volatile components in the silica gel are eluted, and the eluent is distilled under reduced pressure to obtain the licorice extract.

Description

technical field [0001] The invention belongs to the technical field of chemical instruments, and in particular relates to a water vapor extraction device with a silica gel column separation device and an application thereof. Background technique [0002] There are many methods to extract the volatile components of plants such as the active ingredients of traditional Chinese medicine, such as supercritical method. The advantage of this method is that it can be carried out at low temperature without destroying the volatile components. However, the equipment of this method is complex and the extraction cost is relatively high. [0003] Steam distillation refers to the co-distillation of the sample containing volatile components with water, so that the volatile components are distilled out together with the water vapor, and the volatile components are extracted by condensation. The method is simple, effective, and low in cost, and is suitable for extracting medicinal ingredien...
